The Schwarzschild radius of an object is proportional to the mass. Accordingly, the Sun has a Schwarzschild radius of approximately 3.0 km (1.9 mi), whereas Earth 's is only about 9.0 mm. The observable universe 's mass has a Schwarzschild radius of approximately 13.7 billion light years.
(July 2017) The Bohr radius (a0 or rBohr) is a physical constant, approximately equal to the most probable distance between the center of a nuclide and the electron in a hydrogen atom in its ground state. It is named after Niels Bohr, due to its role in the Bohr model of an atom. Its value is 6989529177210670000â 5.2917721067(12)Ã10â11 m.[1][note 1]
